[HLSL] Fix interleaved vector and matrix return types in AST dump (#184888)

HLSL vector and matrix types were previously printed with their closing
syntax (', N>') in 'printAfter', causing them to interleave with
function
parameters when used as return types (e.g., 'vector<float (args), 4>').

This change moves the HLSL vector and matrix closing syntax into
'printBefore' when 'UseHLSLTypes' is enabled, ensuring the type is
printed completely before the parameter list.

Note that address space qualifiers are now printed after the type
(e.g., 'vector<float, 4>hlsl_device'). This is because
'canPrefixQualifiers' in 'TypePrinter.cpp' returns false for these
types.
We cannot easily change this to check 'UseHLSLTypes' because
'canPrefixQualifiers' is a static method and does not have access to the
PrintingPolicy at that point.

Fixes interleaved output in HLSL AST tests.
